A dictionary of string to the four basic Lua types: string, boolean, number, table.

Note that the API returns tags as a simple table, meaning any modifications to it will not propagate back to the game. Thus, to modify a set of tags, the whole table needs to be written back to the respective property.

Tables inside Tags that have numeric keys but are not sequences (e.g. tags = {foo = {nil, "something"}} or tags = {bar = {[4] = "cat"}}) will have their keys converted to strings when read back from the game (e.g. {foo = {["2"] = "something"}} or {bar = {["4"] = "cat"}}). Only sequences without gaps will have their keys maintained as numeric.
